SPOILER ALERT(HOW MANGA ENDS)
For me Domestic na kanojo is a great read. It really show how people face ups and downs in life, what it means to be in a relationship(really shows struggles of relationships), how hard it is to make your dream come true and tough situations that people actually faces in real life. Many people rated this manga between 1-3 and I do relate to them somewhat. I personally feel that author build up the hype so much as to who he will end up with that it lead to frustration among a part of fanbase in the ending. I also feel that ending was a little rushed and author could have added 2-3 more to adjust the fast pacing. If I am to be honest I feel like both Hina and Rui won in the end and this lead to people getting pissed. But I really enjoyed the manga and it kept me wanting to read more. If someone ask me to how good this manga is I would it's spicy and a really great read (However I will warn him to read last few chapters at own risk).

Well this is the first time I have written a review for a manga so it might be bad but tried to express to the best of my ability :)
